  1. I create a handler where I want to subscribe / unsubscribe consumers: type TBSEvent<T> = reference to procedure(const obj: T); IBSRemoteMessageController = interface ['{1C7ECC50-3CA2-41A0-B230-0E9FE4CF9BE4}'] procedure Subscribe(AHandler: TBSEvent<IBSRemoteMessage>); procedure Unsubscribe(AHandler: TBSEvent<IBSRemoteMessage>); end; Now in my implementation of IBSRemoteMessageController I keep a list of these events. Unfortunately it looks like when I try to Unsubscribe() I get a different pointer even if I pass the same method. The only solution I see here is, that I return a key with the Subscribe() method and then pass this key to Unsubscribe(). Or is there a different solution for this problem? Regards Christian

    THTTPCommandType - PATCH

    I'm about to build a REST API using a TIdHTTPServer. Now even in the latest version of Indy the command PATCH is not listed in THTTPCommandType. Is there a reason for that? Or should a just use PUT for all update requests? To be honest when I read in the internet about the differences for PUT, PATCH and POST there are no unique opinions. So maybe I just use POST do add items and PUT for any updates (partial and complete). Regards Christian
  3. Hi, on my computer I have Kaspersky install by default and I cannot change that. I cannot even change any of the settigs, it's all under control of the system administrators. They already added my major application (EXE file) as exception under "Trusted applications" but I still have the feeling it takes forever after compiling until linking is done and my application started. Personally I would like to stop Kaspersky completely, but no chance for that. So is there another setting that should be changed on a developer machine? Regards Christian

    Cyrillic characters in URL

    So this fix will be with the Indy version that comes with Delphi 11? Christian

    Cyrillic characters in URL

    I think, I found the answer myself now: https://stackoverflow.com/questions/24861793/indy-http-server-url-encoded-request When I add this code, my search string is correct. So probably nothing changed here since 2014. Christian

    Cyrillic characters in URL

    I use a TIdHTTPServer and have problems with decoding GET variables. The url in the browser looks like this (contains cyrillic characters): Then in the RequestInfo the UnparsedParam and the QueryParams have the value 'search=%D0%90%D0%BD%D1%82%D0%BE%D0%BD&language=ru' In DecodeAndSetParams this is parsed but I don't get the correct results: The request comes from the browser and I didn't change any properties. So I'm not sure how to proceed. I think Indy uses the wrong encoding but I'm not aware, where I can change that? And will all browser use the same encoding? Or do I have to Parse the QueryParams myself? Christian

    ExtractHeaderFields with special characters

    I use Delphi 10.4.2 and the Indy library coming with the default installation. I found that I can set the "Decode" parameter of ExtractHeaderFields() to false, then it works fine. Christian

    ExtractHeaderFields with special characters

    Ok, the request that comes with this malformed Content-Disposition is created by another Delphi application where I use Indy components. The code looks like this: mPartStream := TIdMultiPartFormDataStream.Create; postDataStream := mPartStream; FHttp.Request.ContentType := mPartStream.RequestContentType; for ix := 0 to FPostNames.Count -1 do begin if FPostFiles[ix].IsNull then mPartStream.AddFormField(FPostNames[ix], FPostValues[ix], 'UTF-8').ContentTransfer := '8bit' else mPartStream.AddFile(FPostNames[ix], FPostFiles[ix].PathName, FPostContentTypes[ix]); end; FPostFiles[ix].PathName is the Windows path of a file. Should I encode it on my side? Or do I have to set another parameter to ensure correct encoding? Christian
  9. Hi, I use ExtractHeaderFields() from Web.HttpApp when I parse a post upload. With the following value for "Content" (containing special german characters) this function fails: 'form-data; name="File1"; filename="Test1MitäÄ-Umlaut.pdf"' I get this error: System.SysUtils 33477 TEncoding.GetString System.NetEncoding 1007 TURLEncoding.Decode Web.HTTPApp 2108 ExtractHeaderFields Now I'm not sure if the input is wrong or if I have to use a different function to parse the content of this header (Content-Disposition:). Thanks for any help. Christian

    IDE Memory Usage

    I'm still working with Delphi 10.4.2 and I noticed, that there are two processes DelphiLSP.exe and both take a lot of memory. In addition there is bds.exe which isn't small either. Is this "by default" or can I change that with changing any of my options? Christian

    TPopupMenu with group headers

    Both "problems" are solved by setting Enabled=False for the group header item. Like this the color never changes and clicks on it are ignored. Christian

    TPopupMenu with group headers

    Thanks for all hints. I created a subclass of TMenuItem and did an override of the AdvancedDrawItem method. In addition I set Enabled=False. Themes are not support, but I don't have that anyway in my application. But so far it looks fine: procedure TMenuGroupItem.AdvancedDrawItem(ACanvas: TCanvas; ARect: TRect; State: TOwnerDrawState; TopLevel: Boolean); begin ACanvas.Brush.Color := TColors.Silver.Lighten(50); ACanvas.FillRect(ARect); ACanvas.Font.Color := TColors.SysWindowText; ACanvas.TextRect(ARect, ARect.Left + 3, ARect.Top + 3, StripHotkey(Caption)); end; Christian

    Yes, this is what I need to do (grouping titles). Regards Christian

    TPopupMenu with group headers

    Ok I added a disabled item ("Bearbeiten") in this case, but it's still aligned with all other items. And setting the Break property just adds a vertical line on the left side: So what do I have to do to align the "Bearbeiten" Text at the left and to change the text color/background? Christian

    TPopupMenu with group headers

    Hi, I would like to add group headers in a TPopupmenu. So I can create things like this: Are there any properties I didn't find yet in the standard VCL? Or can I do that with some additional methods in a TPopupMenu subclass? Christian
